title: 3-Hy-droxy-anilinium p-toluene-sulfonate.
abstract: The asymmetric unit of the title salt, C6H8NO(+)·C7H7O3S(-), contains two cations and two anions. In the crystal, the cations and anions are linked through extensive N-H⋯O and O-H⋯O hydrogen-bonding inter-actions, which result in R 4 (4)(18) and R 2 (1)(4) ring motifs, forming a three-dimensional network.
